Forced lubricating device for through type vehicle interaxle differential

Abstract

The invention relates to a forced lubricating device for a through type vehicle interaxle differential, belonging to vehicle lubricating devices. The forced lubricating device is characterized in that the front outer step face of a front case of the interaxle differential and the rear outer step face of a rear case of the interaxle differential are respectively provided with an annular oil grooveI, the outer groove edges of the oil grooves I are oil duct ribs I, and an oil hole is arranged at the bottom of each annular oil groove and correspondingly communicated with the front part and the rear part of the inner cavity of the interaxle differential; the front inner wall and the rear inner wall of an outer case of the interaxle differential are respectively provided with an annular oil groove II, the inner groove edges of the annular oil grooves II are annular oil duct ribs II, and a front forced oil duct and a rear forced oil duct are correspondingly formed between the oil duct ribs II and the oil duct ribs I; and a roller bearing race on the outer case of the interaxle differential is provided with a front left oil hole communicated with a left cavity of the outer case of the interaxle differential, the left part of the rear annular face of a bearing block is provided with a left oil outlet groove through which lubricating oil flows into the inner cavity of the interaxle differential. by the forced lubricating device, the interaxle differential is well lubricated, the phenomena of abrasion and burnout are reduced, and the service life of the interaxle differential is prolonged.

Description

technical field [0001] The invention belongs to an automobile lubricating device, in particular to a lubricating device for an automobile through-type inter-axle differential. technical background [0002] In heavy-duty trucks, gear splash lubrication is used for the lubrication of the through drive axle differential assembly, but the inter-axle differential assembly is arranged above the axle, and the splashed lubricating oil can easily flow back to the axle housing, and the The gears in the differential assembly are not fully lubricated, and the gears are easily damaged. When the heavy truck moves on the uneven road, the inter-axle differential starts to work. Due to poor lubrication, the inter-axle differential is easy to burn Dead, leading to the failure of the inter-axle differential, which not only reduces the utilization rate of heavy trucks, but also increases the amount of maintenance and production costs.

[0002] In heavy-duty trucks, gear splash lubrication is used for the lubrication of the through drive axle differential assembly. However, the inter-axle differential assembly is arranged above the axle, and the splashed lubricating oil can easily flow back to the axle housing. The gears in the differential assembly are not fully lubricated, and the gears are easily damaged. When the heavy truck moves on the uneven road, the inter-axle differential starts to work. Due to poor lubrication, the inter-axle differential is easy to burn dead, leading to the failure of the inter-axle differential, which not only reduces the utilization rate of heavy-duty trucks, but also increases the amount of maintenance and production costs
